input-append [re-opened]

[robertmain]

I re-opened this issue because im still having issues with it

Here is my markup: http://pastebin.com/huCDRy9u

For some reason when i try to use input-append with a button i get something like this: http://imagebin.org/211163
Notice how the button doesn't straighten its left edge to go with the text input box?
Note: This happens even when i copy the HTML from the official docs

I fixed it by downloading another copy of the css - it mustve gotten corrupted...
